- =====================
- TableGen Deficiencies
- =====================
- .. contents::
- :local:
- Introduction
- ============
- Despite being very generic, TableGen has some deficiencies that have been
- pointed out numerous times. The common theme is that, while TableGen allows
- you to build Domain-Specific-Languages, the final languages that you create
- lack the power of other DSLs, which in turn increase considerably the size
- and complexity of TableGen files.
- At the same time, TableGen allows you to create virtually any meaning of
- the basic concepts via custom-made back-ends, which can pervert the original
- design and make it very hard for newcomers to understand it.
- There are some in favour of extending the semantics even more, but making sure
- back-ends adhere to strict rules. Others suggesting we should move to more
- powerful DSLs designed with specific purposes, or even re-using existing
- DSLs.
- Known Problems
- ==============
- TODO: Add here frequently asked questions about why TableGen doesn't do
- what you want, how it might, and how we could extend/restrict it to
- be more use friendly.
